 ## MicroSD card files
 
-Your PortaPack has a slot for a memory card. You need to provide a MicroSD of at least 4GB or bigger (16GB is recommended, over 32GB will be ommited due the limits of the FAT32). This is necessary for certain functionality, like the world map, GPS simulator, and others. You need to uncompress (using [7-zip](https://www.7-zip.org/download.html)) the files from `mayhem_vX.Y.Z_COPY_TO_SDCARD.7z` to a FAT32 formatted MicroSD card.
